Dedicated power

I encourage the OP to provide 30 amps to the P’sound amp and a separate feed for everything else. “Too much” would serve you better than not enough. I won’t advise on panel connections. I’m gonna follow someone’s suggestion concerning which leg the fridge and chest freezer are on.

An amp having two 15A cords, in some form or another, demands 30A of feed. That said, two pro electricians active on the Polk forum recommend “never exceed 80% of a circuit’s capacity.” My HT will one day have its own breaker panel, another story for another day.

I ran three dedicated 20A circuits for my 5.5 HT. One* circuit feeds the APC H15 that powers and protects all low current devices. The other two** circuits power 6*** amps and 5 powered subs that 4 Furman MP-20s turn one channel at a time. I wish I ran a 4th circuit but I won’t because the current room isn’t it’s final home - another story for another day. *on one leg
** on the other leg
*** adding a 7th amp when I mod/bi-amp the surrounds

I haven’t and don’t plan to finish reading this thread’s comments as it seem there are as many opinions as people offering advice. You have my example that was worth the work.
My best to whatever you decide. Tony.

for the Parasound hca 3500 I wouldn’t be surprised if dealers aren’t telling customers the unit should be fed from a 120V 30 amp circuit. Over the phone Parasound Tech support maybe saying the unit needs to be fed from a 120V 30 amp circuit. I doubt they would put it in writing. If they did they should specify the receptacle outlet would need to be rated at 30 amps.




Doesn't the parasound hca3500 have dual plugs one for each channel?

Just DO IT MAN! You will never regret it!
